Hi guys,

I haven't posted on here for a while. I've got a 1.6 2006 stilo I'm nursing. Slowly getting her right. I drive another car so she can rest while I fix here and there. So now and then I take her for a couple days too keep her legs stretched😂

Quick question, I read somewhere that a temp sensor can cause fueling issues with Ecu, is this true?

I don't have a CEL, I don't have a problem with my temp Guage, always goes to sit on middle when she's at temp. Fan goes on and off when needed. But when she's cold and you start her, she will crank a few times especially when cold. Then I must try a couple times before she starts. Then I let her idle abit, she will have a misfire idle(when revving it doesnt misfire), eventually after about a couple, the idling will smoothen out. Then you drive her and she don't misfire but you can just feel like there a fueling issue.

Say when you pull away like normal, then give her a Rev when changing the gear(clutch pedal is pressed), she will give a 'pop' or backfire out the exhaust. This only happens when she's cold. When driving and you get to around 2500rpm then the revs get jump, then she will be alright if you take her higher.

I used to get a throttle body fault but not getting it anymore and no repairs was done to throttle body.i don't get temp sensor codes. I get very seldom a p0606 after she struggles to start. Not always.

Is it Ecu or sensor related?

O2 sensors replaced and crank sensor.

Worse when cold
ECU error if its been cranking a long time
I would start by measure the battery cranking volts

but I have never owned a Silo so wait for the experts to chime in

Battery is a brand new battery i bought.
It's the battery for the stilo according to their info.

Extra symptom but happens really seldom ly, this morning I started her, she ran low on idle, like she's at operating temp so the engine struggled to stay on. Pressing the accelerator, pedal is dead. CEL on. Switch car off and start again, starts and has high Rev like normal when she's cold.

I'll read codes later, I just moved her because she was in the way of another car. It's still early hours of the morning here in South Africa

p0606 is an internal computer fault 90% of the time its due to low voltage and/or bad earth

might be nothing more than the battery dropping too low due to extended cranking and not relevant

if it was me I would from cold put some jump leads from another car and see how it starts

post a picture of the sparkplugs in order would tell us a lot, running rich, lean, one cylinder different an so on

any sensor that is involved with controls the fuelling will effect the running. but its a big leap to suspect the coolant sensor. The best way to check is to read the live data and wiggle its cable,

Thank you for the reply

I'm actually going to service her this month end. I'll send pics of her plugs later when I get I chance.

Your explanation of p0606 makes sense because it normally comes when she cranks long. When she cranks long then engine will crank slightly slower say on 2nd or 3rd try but will come back up.
